Abstract
The utility model discloses a kind of ellipsograph, comprising: fixed cone, the first rotating shaft, the second rotating shaft, top board, lettering pen, tape measure, chute, the first track, the second track, the 3rd track; Fixed cone is provided with chute, first rotating shaft and the second rotating shaft are installed in chute, the upper end of the first rotating shaft and the second rotating shaft is provided with top board, the middle part of the first rotating shaft is provided with the first track, the middle part of the second rotating shaft is provided with the second track, be provided with the 3rd track in the middle part of lettering pen, the first track, the second track, the 3rd track are connected by tape measure.This Ellipsograph structure is simple, draws elliptical velocity fast, drafting standards, and size as required can carry out oval drafting, easy to operate.
Description
Technical field
The utility model belongs to study article technical field, particularly relates to a kind of ellipsograph.
Background technology
In daily study and work, often need to draw ellipse, can simply draw by hand in the occasion had, the accuracy of figure is not high.When mechanical drawing, adopt Approximate, drawing method is loaded down with trivial details, in the teaching in middle school, the skill of drawing sub-elliptical is complicated, is not suitable for Middle school students ' learning, although existing ellipsograph exists, the size of ellipsograph is fixed, and the ellipse drawing different size is still insoluble problem.
Utility model content
The object of the utility model embodiment is to provide a kind of ellipsograph, and be intended to solve ellipse and be difficult to draw, picture very complicated, is not suitable for Middle school students ' learning, and ellipsograph size is fixed, and can not draw the problem needing size ellipse.
The utility model is achieved in that this ellipsograph comprises: fixed cone, the first rotating shaft, the second rotating shaft, top board, lettering pen, tape measure, chute, the first track, the second track, the 3rd track; Fixed cone is provided with chute, first rotating shaft and the second rotating shaft are installed in chute, the upper end of the first rotating shaft and the second rotating shaft is provided with top board, the middle part of the first rotating shaft is provided with the first track, the middle part of the second rotating shaft is provided with the second track, be provided with the 3rd track in the middle part of lettering pen, the first track, the second track, the 3rd track are connected by tape measure.
Further, described chute is provided with rule.
Further, the first described rotating shaft and the upper end of the second rotating shaft are provided with locating piece, after regulating the distance of the first rotating shaft and the second rotating shaft, the first rotating shaft and the 3rd rotating shaft are fixed, be convenient to draw by locating piece.
Fixed cone is fixed on writing paper, according to change oval size, regulate the distance of the first rotating shaft and the second rotating shaft, institute's comprehensive analysis of conditions of CUN KOU pulse and skin of the forearm is undertaken by rule and tape measure.Conveniently can draw the ellipse of different size, save the time of picture.
The advantage that the utility model has and good effect are: this Ellipsograph structure is simple, draw elliptical velocity fast, drafting standards, and size as required can carry out oval drafting, easy to operate.

Fig. 1 is the structural representation of a kind of ellipsograph that the utility model embodiment provides;
In figure: 1, fixed cone; 2, the first rotating shaft; 3, the second rotating shaft; 4, top board; 5, lettering pen; 6, tape measure; 7, chute; 8, the first track; 9, the second track; 10, the 3rd track; 11, locating piece.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with drawings and the specific embodiments, application principle of the present utility model is further described.Fig. 1 is the structural representation of a kind of ellipsograph that the utility model embodiment provides, as shown in the figure, the utility model is achieved in that this ellipsograph comprises: fixed cone 1, first rotating shaft 2, second rotating shaft 3, top board 4, lettering pen 5, tape measure 6, chute 7, first track 8, second track 9, the 3rd track 10; Fixed cone 1 is provided with chute 7, first rotating shaft 2 and the second rotating shaft 3 is installed in chute 7, the upper end of the first rotating shaft 2 and the second rotating shaft 3 is provided with top board 4, the middle part of the first rotating shaft 2 is provided with the first track 8, the middle part of the second rotating shaft 3 is provided with the second track 9, be provided with the 3rd track 10, first track 8, second track 9 in the middle part of lettering pen 5, the 3rd track 10 is connected by tape measure 6.
Further, described chute 7 is provided with rule.
Further, the first described rotating shaft 2 and the upper end of the second rotating shaft 3 are provided with locating piece 11, after regulating the distance of the first rotating shaft 2 and the second rotating shaft 3, the first rotating shaft 2 and the 3rd rotating shaft 3 are fixed, be convenient to draw by locating piece 11.
Fixed cone 1 is fixed on writing paper, according to change oval size, regulate the distance of the first rotating shaft 2 and the second rotating shaft 3, institute's comprehensive analysis of conditions of CUN KOU pulse and skin of the forearm is undertaken by rule and tape measure 6.Conveniently can draw the ellipse of different size, save the time of picture.
The advantage that the utility model has and good effect are: this Ellipsograph structure is simple, draw elliptical velocity fast, drafting standards, and size as required can carry out oval drafting, easy to operate.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
